Microsoft is testing a new performance feature for Windows 11 that temporarily maxes out your CPU whenever you open an app or click the Start menu. The feature, called “Low Latency Profile,” spikes processor frequency for one to three seconds during high-priority actions, then drops back down—and early results are hard to ignore.According to Windows Central, which first reported the feature, app launch times for built-in apps like Edge and Outlook could improve by up to 40%. The Start menu and context menus are seeing even bigger gains—up to 70% faster.
Apple has done this for years, and nobody complained
Microsoft VP Scott Hanselman stepped in over the weekend to defend the approach after critics called it a band-aid fix. His response was blunt: “Apple does this and y’all love it. Let Windows cook.” He’s not wrong—macOS uses Apple’s QualityOfService class to do exactly this, and Android has its own Dynamic Performance Framework. Windows is just late to the party.The feature is part of Microsoft’s broader “Windows K2” engineering push, which aims to make Windows 11 feel meaningfully faster across the board—not just on paper.
Low-end laptops stand to gain the most
Windows Central notes the boost is automatic and invisible to the user. There’s no toggle, no performance mode to dig through—it just fires when needed. Battery and thermal impact are reportedly minimal since the burst is so short.Testing on a deliberately underpowered virtual machine—limited to two CPU cores and 4GB of RAM—showed apps going from sluggish to near-instant after the feature was enabled.The Low Latency Profile is still moving through the Windows Insider pipeline. No firm release date yet, but if testing holds up, it’s the kind of change most users will feel immediately.
